Abstract Objective To access the efficacy and safety of naftopidil in medical expulsive therapy of distal ureteral calculi. Methods A systematic search was performed in Pubmed, Cochrane Library, CNKI, Wanfang database and VIP database to identify RCTs that compared naftopidil and other therapy for distal ureteral calculi. Two authors independently assessed study quality and extracted data. All data were analyzed using RevMan5.0. Results 11 studies with a total of 983 patients met the inclusion criteria. There was a significant overall benefit for stone expulsion rate(RR=1.63, 95%CI 1.32-2.03, P<0.01)and stone expulsion time(WMD=-2.83, 95% CI -3.75--1.92, P< 0.01)in naftopidil group compared with watching waiting group. Compared with α1A adrenergic receptor blockers group, there was no statistically significant differences in expulsion rate(RR=0.97, 95% CI 0.78-1.20, P=0.76)and stone expulsion time(WMD=0.15, 95%CI -0.40-0.69, P=0.59). But naftopidil provided a significantly lower side effects rate(RR=0.52, 95%CI 0.27-0.98, P=0.04). Conclusions Naftopidil can effectively promote the expulsion of distal ureteral calculi. Compared with α1A-adrenergic receptor blockers, there are no statistically significant differences in expulsion rate and stone expulsion time, but with a significantly lower side effects rate.
